To all whom it may concern:

Be it known that I, MARTIN J. Osrnn, a citizen of the United States, and a resident of Ghent, in the county of Lyon and State of Minnesota, have invented certain new and useful Improvements in Strainer Supports and Screens, of which the following 15 a specification. H I v My present invention relates to devices for supporting strainers at the mouths of containers and screening said mouths against in ess of flies, or other foreign matter.

he principal ebjectsof my invention are to rovide devices of the character described which will effectively support the strainers usuallyof the funnel type, at the mouths of containers, such as pails or separator tanks,

and retain them against accidental displacement; supports which may be quickly placed into or-removed from operative relatlon to associated with the containers; and screens the-supports which may "be quickly attached to or removed from the supports; sald screens capable of. preventing ingress of foreign matter into the containers about the strainerswhen placed in pos1t1on.- Otherobjects of my invention are to rovide'devices of the character described w ich are simple in construction, inexpensive to manufacture, durable, and light In weight.

Further ob'ects of my invention will ap- Pearin' the ollowing detailed description, taken in connection with the accompanying .drawing, forming a part of this specifica- 85 tion, and in which drawmg: I -'Figure 1 is a perspective view of a strainer Support constructed accord ng to my invention and disposed in operative relation to a pail. Fig. 2' is a plan view of a screen constructed accordm to my invention. p Fig. 3 is an en argedcentral vertical longitudinal sectional view through the support and: showing the screen as applied Fig-.4 is a perspective view of a detail of the screen. I Fig. 5 is an enlarged sectional viewv on the line 5-5 of 2. a

These sections, for a portion oftheir length from the juncture 7, form a stem 8, as by being in engagement with one another, and twisted as indicated at 9. Each section 6 is arcuated where itsprings from 'said stem providing an annular shaped maidbody 10 to embrace a portion of the funnel.

said main body 10, the sections extend in parallel relation 'for a short distance, preferably in engagement one with the other, and in the longitudinal axis of stem 8, after which they are bent in opposite directions,

preferably at right angles, with the terminal portions 11 adapted to embrace the top of the container A. -These sections 6 are secured together, as by a rivet 121a ghat ortion of body 10 opposite to-stem inch terminal portion 11 may be adapted to gri the container-A, as by "being slit longitudigglly to provide stems 13 and 14, these stems in is o hook shape and adapted to rest upon the upper margin of the container A and engage the outer side of'its wall, while the stem 14' is bent downwardly and outwardly with respect-t0 main body 10 to engage the inner side of the wall of the container. If desired, the support may be made of metal having a slight spring action, or the stems 13 and 14 may be spring-tempered and it is'preferred to so arrange said stems one with respect to the other that when-placed into operativerelation to the container, they bent in such a manner that stem 13 are moved out of a normal position causing their free end Portions to bite slightly the spect to the stem 8 so that its maqor portion the container A.- 1,
